hello i have just got a sony fx100, i bought it used

At first..i am worried about noisy image when panning. When record at 6mbp it is terrible. At 100 no, but it is really evident the rolling shutter (all at 4k)

To ax100 owner..are there any things to do to get the best out of the camera berfore everything? I have always used mirrorless..so camera may need different treatment

Also..i want to understand if these things are nomral or this is a faulty copy

Thanks
 
Small chip, old camera...most phones have better quality today.

Panning would have nothing to do with noise - but, as general advice, use it at the highest-quality recording settings with as much light as possible (and don't apply too much gain).
 
Your description is a bit convoluted but after looking at the manual I understand.

The short answer this is normal, nothing wrong with the camera.

The long answer is rapid panning while filming 4k is challenging in two respects. The first is it takes longer for the camera to scan the sensor in 4k which is more noticeable during panning, resulting in rolling shutter.

The second is compression artifacts are more visible when panning because the image is rapidly changing so lower bitrate will exhibit more defects. While 4k60p will capture motion better it needs a higher bitrate but the camera is recording in a lower bitrate no doubt to reduce the stress on the processor.

This is true of most cameras to varying degrees. To alleviate this, don’t pan, pan slower or film at 1080p.

it is convoluted as the really first shot..with lens zoomed and moving around i see horrible artifact all over..it seemed broken. Then in moro controlled situation seemed better..a part of the terrible rolling shutter
I paid for it 300 hundreds ..at that priced i wanted to have i tried with a camcorder, as i always used mirrorless. But don't seems a good idea though..or need to find a use for it

No, you did well. Although this camera model was released almost twenty years ago there sadly haven't been any significant hardware improvements in camcorders since. Manufacturers just haven't been interested in upgrading camcorders. Still the same 30P, 1" sensor and 12X lens as on Sony's "later" models in this category. Really, only thing they've upgraded is the price.

If you think this camcorder is in the same league as the AX700, NX80, Z90, Z190, Z280, or Z150, you are sadly misinformed. The newer camcorders are superior in terms of both performance and features.

BTW, in case you weren't alive in 2003, 20 years ago camcorders were SD only, mostly analog no high frame rates, no progressive, no HDMI or SDI , they recorded on tape, had crude AF if any at all, low-resolution viewfinders, no flip-out LCD, no LOG, no HD, no 4K, no variable ND, sometimes no ND at all, XLR inputs were rare, only one or two channels of audio, no timecode jacks, no wireless connectivity, etc.

it's not 20 years!!!it s a camera of 2014..so 10 years
Then sony release ax700, which have some better specs, autofocus for example..but mainlyìi think, same iq

Sorry dont understand this, can you explain me different please?thanks

60p records twice the frames compared to 29/30p. This captures motion better but it would need higher bitrate otherwise the video has to be compressed more. The ax100 manual states 4k30 use 100mbs and I believe 4k60 uses 60mbs

so you saying to use all at the best spec?

I'm explaining what I'm seeing in the specs. It's your choice whether you'd rather have rolling shutter or compression artifacts or lower resolution or buy a better camera. It's up to you.

i am sorry but i haven't properly undertood what you mean.. may be i should buy a better camera ! :)

That makes two of us, I don't understand what you don't understand. But in the grand scheme of things nothing we do actually matters. So feel free to do whatever you want.

ok i don't understand this
"It's your choice whether you'd rather have rolling shutter or compression artifacts or lower resolution"
1 roling shutter
2 compression artifcat
3 lower resolution
i understand that 1 and 2 can be related (but i woul dlike to understand what are the setting that lead to lower resoluiton and whatt are the one that leads to artifacts
Then the point 3..lowr resolution.what for?

sorry english is not my language but it is your, probably it is hard for me to understand you because of this
 
There's no setting on the camera that you can change to improve rolling shutter. It is whatever it is. However, with that said, I have no idea if rolling shutter is a problem worth worrying about on the AX100 or not. But I really doubt it that it is. I wouldn't give rolling shutter a minute's thought.

As for resolution . . . set the camera for 4K and use the best codec the camera offers. You can set it and forget it.

But you still won't get good results without using the right exposure settings (gain, f-stop, shutter speed), the best focus settings, and paying attention to white balance. That is where you should focus your effort as you learn the camera -- because those are settings that need constant monitoring and adjustment and will make all the difference in the quality of the images you capture.
 
Sure.i am.new to camcorder but i have been using mirrorless for years, and it is the same!don t know if the age of the cam affect the iq anyway....btw why you say you don t give attention to rolling shutter?

Because there is nothing you can do about it except choose a different camera. So either accept it or don't shoot. With the exception of shooting lightning, I've never found rolling shutter to be a problem on any of the dozens of cameras I've owned in the last 15 years. It is 99% a non-issue.

I've noticed that the more someone obsesses about rolling shutter, the less likely they are to be able to shoot nice-looking video no matter what camera they have.

In general most cameras have less rolling shutter when filming at 1080p rather than 4k. Because the sensor can be scanned quicker. You can test to see if it's true for your camera. Rolling shutter isn't important to most people because they don't do a lot of quick pans. Many people like to dwell on the short comings of their camera. Identify what is truly important then make the appropriate compromises.

yes, sorry, did mean almost ten years but still, no change in lens, framerates and I think IQ. I also think I’m not the only one looking for a light 4k 60p camcorder with a wider lens.
